SPECIFICATION forming part of Letters Patent No. 269,931, dated January2, 1883.

Application filed November 27, 1882. (No model.) f

To all whom it may concern Be it known that I, ALPHoNSo S. HARRIS, ot'Chelsea, State of Massachusetts, have invented an Improvement inGas-Burners, of which the following is a specification.

This invention relates to gas-burners; and it consists in theconstruction and combination ofthe divers devices embodied therein, ashereinafter more parlicularlyand fully set forth and claimed.

Figure l is a perspective view ot' a gasburner embodying my invention.Fig. 2 is a longitudinal "ertical section of Fig. l, taken through thecheck-lever and one of the radial arms, and also showing in elevation asection of a supply-pipe and its stop-cock connected with the burner.Fig. 3 is a horizontal section taken, as on line W, Fig. 2, through thepillar, the check stem and lever, and the radial4 arms, the tips andtheir supportingsockets being shown in central vertical sec.- tion. Fig.et shows in elevation the check Stem and sleeve as detached from theburner and from each other. Fig. 5 shows the same parts as -in Fig. 4,but as connected for use and in longitudinal section.

[n Said views, a represents the pillar of the burner, shown as mountedupon a supply-pipe, b, in which is arranged the usual stopicock o, bywhich the. supply ot' gas is let on or shut oft' from the burner. Inpillar a are secured the radial conduit-arms d, upon the outer ends ot'which are mounted the sockets e, which receive and support the tipsf, asshown.

For the purpose of checking and regulating the dow ofgas to the tipsafter it has passed cock c, I employ a sleeve. lt, which is formed withan enlarged externally-threaded section, t', -anda diminished smoothsection, j. This sleeve is secured in pillar a by engaging correspondinginterior screw threads formed therein, and it may be locked firmly inposition in the pillar by seating its shoulder, formed at theintersection ot' the enlarged portion t' and diminished portionj,againstacorresponding shoulder in the pillar, as shown in Fig. 2; or itmay t so closely in the pillar as not to be disturbed when thecheck-stem is actuated. rihe axial passage in said sleeve isscrewthreaded nearly throughout its length, as

shown in Figs.2 and 5, and a stem, m, is threaded upon its exterior tofit closely but move freely in the sleeve. in the lower portion of saidstem is formed an axial passage, as shown in Figs. 2 and 5, with whichthe transverse passages u directlycom'municate, said transverse passagesbeing at the same distance apart as are similar passages, Z, l'orined insleeve h. In said sleeve is inserted a check pin or screw, t, forconvenience of both forming holes Z in the-sleeve and a in stem m, andalso for adjusting the check in the former, said sleeve being tirstScrew-threaded in its interior, and then said pin tbeing inserted, afterwhich stem m -is inserted in the sleeve and rmly seated upon pin t, whenthe transverse holes l n are drilled through the wall of both the sleeveand stem, and thus exactly correspond. When thus prepared the sleeve isinserted in the pillar by means of a screw-driver, the base ofthe sleevebeing-slotted, as shown at 7c, for that purpose, when stem m may beinserted through the axial coincidentlythreaded passage in the head ofthe pillar', and is turned into the sleeve till arrested by pin t, whenthe actuating-lever o is secured in the head of the stein, as shown,vthe Several parts being so arranged in relation to each' other thatwhen lever c is moved in one direction against an arm, d, the gas willbe 1 n full iiow to tips f, and when said lever is 4moved in theopposite direction against one of said arms the tlow of gas to the tipswill be reduced to the lowest desired quantity, thereby rendering itpractical to regulate the tlW ot' gas at any desired pointI between afull head and such minimum quantity.

Instead ot' threading stem m in the head ot' pillar a, it may be packedtherein, if desired.

. The iioiv of the gas through pipe b, slee\'e It, Stemra, holes n l,into the chamber in pillar a, around the upper portion ot' the sleeveand stem, and thence through arms d to the tips, will be apparent froman inspection ot' the drawings.

By arranging the'arms (l radially in the pil- 1ar,as shown, thetransverse openings l n may be sufficiently Small to ai'ord therequisite check to the iow of gas, and yet not be entirely closed by therotation ot' the stem when lever IOO '1r is moved from tlie position ofmaximum tlow of gas to the opposite position against another arm d, asbefore explained.

I claiin as my invention- 5 1. The combination of hollow pillar a.,sleer'e h, and stein m,l1aving, the respective axial and transversepassage, and lever c for actuating said stem, substantially asspecified.

2. In combination with sleeve h and stem m, 11a-ving,rtherespectiveaxial and transverse passages, and means for actuating saidstem, the stop-pin t, arranged in said sleeve to arrest the movement ot'the stem therein when the respective transverse passages l 1t arecoincident, substantially as specified.

3. In combination with pillar a, sleeve h, stem m, and lever c, allarranged to operate as described, a plurality of radial conduitarms d,arranged around said pillar to gage and control the movement of saidlever and the requisite relative adjustment ot' the transverse passagesin said stem and sleeve, substantiall5T as specified.
